On October 31, 1993, Schwartz, Brenda L.; Erickson, Bruce W.; Bursey, Maurice M.; Marbury, G. Dean published an article.SDS of cas: 53838-27-0 The title of the article was Dependence of benzyl alcohol loss on C-terminal amino acid in tandem mass spectrometry of N-protected tripeptides. And the article contained the following:
The effect of the basicity and chain length of the C-terminal amino acid on the fragmentation of N-protected tripeptides was investigated with a hybrid tandem instrument. Pos.-ion unimol. decomposition and collisionally activated decomposition studies on the [M + H]+ ions of a series of N-benzyloxycarbonyl (Z)-protected tripeptides Z-Gly-Leu-Xxx-OMe and Z-Gly-Pro-Xxx-OMe (Xxx = Arg, Lys, Orn, Gln Glu) indicate that substitution of Leu with Pro at the second position in the tripeptides facilitates the loss of benzyl alc. (108 u) from the precursor. Addnl., higher gas-phase basicity and longer chain length of the C-terminal side-chain group promote the formation of the [M + H – 108]+ ion. The experimental process involved the reaction of (S)-5-tert-Butyl 1-methyl 2-aminopentanedioate(cas: 53838-27-0).SDS of cas: 53838-27-0
